MIC5800YN

Overview

The MIC5800YN is a 4-bit parallel-in latched driver manufactured by Microchip Technology, designed for high-side power switching applications. It operates within a supply voltage range of 5 V to 12 V and supports a maximum output current of 500 mA per channel. The device features non-inverting logic compatible with TTL series standards and includes one circuit configuration. It functions effectively across an operating temperature range from -40°C to +85°C, consuming a typical working power supply current of 1 mA.

Feature Summary

• Integrates four independent high-side switching channels for load driving
• Maintains output state via internal latching mechanism after input signal removal
• Accepts parallel digital inputs with non-inverting logic polarity
• Compatible with standard TTL logic families for direct interface

Applications

• High-side power distribution in industrial control systems
• Driving inductive loads such as relays or solenoids
• Parallel data latch interfaces in embedded hardware
• Automotive accessory power management circuits

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm package type and temperature grade accuracy. Ensure that the procurement source provides valid RoHS compliance certificates and moisture sensitivity level information. Cross-reference the manufacturer part number with authorized distributor catalogs to prevent counterfeit components. Confirm that the supplied units match the PDIP-14 physical dimensions and pinout specifications required for the target PCB layout.

Selection Notes

Select this component when a compact solution for multiple high-side switches is required without external discrete transistors. The internal latching feature reduces microcontroller I/O pin usage by maintaining state without continuous signaling. Consider the 500 mA current capability for moderate load requirements. Verify that the 5 V to 12 V supply range aligns with the system's available power rails and that the TTL compatibility matches the controlling logic family.

Part Context

This device belongs to the MIC5800 series of power management integrated circuits focused on load driving and distribution. It serves as a specialized alternative to discrete transistor arrays, offering reduced board space and simplified design complexity. The component integrates protection features inherent to high-side switching architectures, providing reliable operation in environments requiring precise control over multiple electrical loads simultaneously.
